Pool swim stops recording distance mid activity

I've had this scenario a few times now...

Mid swim set my watch will stop recording distance

I'll press the 'back' button to start a new interval as usual, but the distance for this new interval will be stuck on 0 for the duration. Even if I end the activity and start a new one the problem persists. Come back the next day and everything is working again.

See below - the intervals highlighted are recorded as rest?

I have the same problem (Garmin 945)

Watch does not count pools that are in the workout as kick or drill (i.e. only legs or limited arm work).

I think it started when Garmin introduced additional fields to swimming workout (Pool Swim Workout Enhancements).

Today I did a workout that I created a year ago. And everything is ok. When I switch to drill in training, the "Drill Log" immediately starts. I swim a given length according to the training, I give Lap and I have it passed, I do not have to choose the length because I have it specified in the training.I also did the training today, which I created today. When switching to tdrill, it does not start the "Drill Log".

I have been in correspondence with Garmin all day. I have sent them videos showing the training run planned from the web and mobile app. Then I have sent them the logs from the watch.

Thank you for contacting Garmin Poland.
